Multiifo coincident rate estimation
This page details the testing done to the coinc_rate.multiifo_noise_coinc_rate function to check that noise rates are being calculated correctly
Note that there is some 'blocking' (grouping of templates with similar duration) in order to obtain better statistics for the triple coincident events
This 'overestimate' is the predicted rate divided by the true rate, there may be a small bias due to the true rate being an integer
This rate can be used as a benchmark/constant standard for scaling rates from other ifo combinations and/or data periods to obtain numbers of order 1.
